Abramson/Lisker VOT stimuli for labial place of articulation
10 ms steps; positive 140 is missing
"P" in filenames stands for plus, "M" for minus
The following seem to be about 5 ms too long:
P30, P50, P90, P100, P110.
This discrepancy is probably due to the combination of
recording conditions used to make these versions.
A few ms of silence precede each syllable.
